Expansion requirement of 15%

Increase installed capacity in Sao Paulo State by 15% (400 MW), either in greenfield projects or through long term

purchase agreement with new plants

The obligation was supposed to be accomplished by December 2007, however AES Tietê was not able to comply with this

requirement due to the following restrictions:

– Insufficient remaining hydro resources within the State of São Paulo

– Environmental restrictions

– Insufficiency of gas supply / timing issue

– More restricted regulation on energy sale established by the New Model of Electric Sector (Law # 10,848/2004)

which eliminated the self dealing

• In August 2008, Aneel informed that the issue is not linked to the concession

• Popular law action against Federal Government, Aneel, AES Tietê, and Duke

– Status: Defense filed on first instance in October 2008 by AES Tietê. In December, 2008, the author replied AES

Tietê defense and, since this, both parties are waiting judge movement about the necessity of proves production

• On July 27, 2009, AES Tietê was notified by the State Government Attorney’s Office to present arguments on compliance

with the expansion obligation

– The Company filed a response on July, 29th, which exhausts the procedure for notification. Possible deployment

depends on new manifestation of the Prosecution

• Carbon Credit– Clean Development Methodology (CDM) approved by United Nations Framework Convention on Climate Change

(UNFCCC), allows up to 10,000 hectare reforestation on reservoir borders– AES Tietê is seeking for good business opportunities, and has not transacted credits so far

• Reforestation– One million of seedlings production in seed-plot of Promissão hydroelectric power plant– Donation of seedlings to the society, rural producers, city halls, and non-governmental organizations

• Fish Farming– Reproduction of 2.5 million fishes in 10 reservoirs of AES Tiete's plants

• Archeological Park– Community involvement into archeological artifacts conservation and better understanding of its scientific

importance– Social access to the archeological history of the reservoir area
